GRAIN-BINDER.

SPECIFICATION forming part of Letters Patent: No. 374,434, dated December 6, 1887.

Application filed October 19, 1886. Serial No. 216,684. (No model.)

To all whom it' may concern:

Beit known that LGEORGE H. SrULDING, a resident of Chicago, in the county of Cool; and State of Illinois, have invented certain new and useful Improvements in Grain-Binding Machines,of which the following is a specitication.

lThis invention has reference to that class of graiirbinding machinesin which the vibrating 1o needle or binderarm, rising through the deck or binding-table against the gavel, is opposed by a vertically-movable compressor, which falls at the proper time to permit the discharge of the bound bundle from the table thereover in the same general manner as in machines of the well-known A1)plebytype.

The invention relates to improved means for tripping the binder driving-gear into action through the instrumentality of the gavel, and

2o to improved means for controlling the operation of the compressor.

As the breast-plate overlying the grain-pas-- sage, the tying mechanism, and lthe various other parts common to bindingmachines of this type may be of ordinary construction and are foreign to the present invention, they are omitted from the drawings, which illustrate only those parts which have connection with the invention.

In the accompanying drawings, Figure l representsa rear end elevation of the principal parts of a binding-machine having my improvements embodied therein. Fig. 2 is abot' tom plan view of the same. Fig. 3 is a top plan View of the pit-man and tripping devices through which the binder driving-gear is con-r trolled. Fig. 4 is a rear elevation of the same. Fig. 5 is arear elevation ofthe binding-needle, the compressor, and the devices operating directly therewith. Fig. 6 is a rear elevation of the pivoted dog or cam used to control the compressor. Fig. 7 is an edge view of thesame and of the needle on which it is mounted, the parts being shown partiallyin section. Fig. 8 is a rear side elevation of the needle. Figs. 9 and 10 are respectively a lower edge view and a rear side elevation of the intermediate arm controlling the compressor. Fig. ll is a top plan view of the binder deck or 5o table. Fig. 12 is au edge view of the same, looking from the front of the machine. Fig.

13 is a side elevation of one of the spring bolts by which the binder-deck is secured in position.

Referring to the drawings, A represents the binder-frame, commonly known as the bindergear standard,77 4made of substantially the same form as in existing Appleby machines, with a tubular arm, a, underlying the grain table to receive the needle-shaft, and a second 6o tubular arm, b, overhanging the grain-table to receive the knotter-shaft. The lower arm is bolted to transverse bars or sills B B,whicl1 are also bolted,as usual,to a supporting bar or rod, C, lying in a fore-aud-aft direction.

D represents the binding-needle,of ordinary form, secured, as usual, to a rock-shaft, E, extended through the lower arm, a, of the binder-frame, and provided at its front end with an operatingcrank, F, fixed rigidly thereon, 7c as usual.

In order to give support to the parts hereinafter described, I provide the frame with an eXtra sill or base-bar, B2, at the front. This sill is bolted at one end to and sustained by 7.5 the rod C, already referred to. At the opposite end it is supported by a sleeve, G, mounted loosely upon the end of the needle-shaft, which is extended for this purpose beyond the needle, as shown in Fig. 2.

To prevent the lateral movement of the sleeve and sill Bf, a pin, c, or equivalent device, is applied to the end of the needle'shaft, as shown.

The extension of the needle-shaft to support the sill is an important feature of my invention.

It is manifest that the form of thc sill and its support may be modified at will, provided only they are sustained by the extended end 9c of the needle-shaft.

H represents the packer-shaft, provided, as usual, with cranks to carry the packerarms. This shaft is mounted in boxes on the sills B B B2, as shown, whereby it receives a firm support and is prevented from springing. The packer-shaft receives a const-ant motion from a sprocketwheel, I, mounted thereon and connected thereto by a spline, or equivalent sliding connection, which admits of the wheel re- Ico maining at rest as the packer-shaft slides forward and backward in adjusting the binder upon the harvester'. A gear-wheel, J, fixed on the rear end of the packer-shaft, imparts motion to a second gear, K, on a short shaft, L, extended through a bearing bolted to the sill, and 'provided at the opposite end with a sprocket-wheel, M, which communicates constant motion through a chain, N, to a large wheel, O, mounted to revolve freely on the knetter-shaft I?.

The shaft I), mounted in the upper end of the gear-standard, will be provided with the usual gear for operating the knotting mechanism and with the arms for discharging the bound bundles. At its rear end the shaft P is provided with a crank, Q. fixed rigidly thereon and connected by a pitman, R, herein described in detail, with the crank F of the needle-shaft.

In order to transmit motion to the needle, I provide clutching devices for connecting the crank Q to the wheel O, whereby the wheel is caused to revolve the crank, which in turn, through the pitman R andA arm F, imparts a vibratory motion to the needle-shaft, causing the needle to rise and fall. The clutching devices just referred to, which form an important part of my invent-ion, I will now describe, referring particularly to Figs. 1, 2, and 3.

The wheel O is provided on its side face at regular intervals with a series of studs or rollers, e, which ordinarily travel freely past the side of the crank Q. On they crank, at the poiutf, there is pivoted a dog, S, having, as shown in Figs. 3 and 4, a lateral projection, g. A spring, L, connecting the dog and the crank, tends to turn the dog upon its pivot in such position that its projection g will stand in the path ofthe rollers e. Vhen thisoccurs, the first advancing roller bearing on the projection g will, through the dog,- impart motion to the crank Q, the crank, with the dog thereon, revolving with the wheel O, and imparting motion, as before explained, to the needle. In order to stop the motion of the crank, it is only necessary to turn the dog S backward on its pivot against thc action of the spring until the projection g is carried out of the path of the rollers, as shown in Figs. 3 and 4, where upon the crank, being released from the wheel O,will cease its movement, although the rotation of the wheel continues.

The crank is required to make but one revolution during the binding of each bundle. In order automatically to effect its stoppage at the end of this revolution and in a definite position, I construct the pitman in the peculiar manner shown in the drawings. Its main portion consists of a rod, i, continued upward loosely into the pitman-head j, and provided in the slot in said head with a nut, k, one end of which is projected laterally beyond the slot in order to encounter the end of the dog S. A spiral spring, m, encircles the body of the pitman, bearing at one end against a loose collar, a, and at the opposite end against a collar, o, adj ustably fixed on the pitman. This spring tends to force the body of the pitman ,the rolls, as heretofore described.

downward and to hold the nut k in the lower end of the slot, in which position its projecting portion Willvencounter the end of the dog S as the latter is brought around by the crank, and act to throw the dog backward out of engagement with the roller of wheel O, as shown in Fig.`l.

To start the binder, it is only necessary to force the lower end of the pitman upward, the effect of which is to carry the nut k upward from under the lower bent end of the dog S, which, being thus released, is turned by the spring into position for engagement with The upward movement of the pitman may be caused by devices of any suitable character connected with the needle or with the compressor in such manner as to be affected primarily by the pressure or resistance of the grain. I recommend, however, for this purpose a constructionsuch as shown in the drawings, and which I will now describe.

T represents the compressor, arranged to swing vertically around a horizontal pivot, o', at the lower end of a rigid stationary arm, U, which lnay be extended downward from the base of the binder-frame, or otherwise supported. The compressor is extended at its heel end beyond the pivot and provided with alip, p, to encounter the arm U and limit its falling motion, and also provided with a laterally-projecting stud or roller, 1', on which a cam on the needle acts to secure the elevation and depression of the compressor at the proper time. 'Ihe needle is constructed, as shown in Fig. 8, with a web or arm extended downward and rearward, and terminating at the rear end in a portion, s, which acts,when the needle is fully depressed beneath the compressor, as shownin Figs. l and 5, to lift the compressor and sustain it in its operative position. On the side face of the needle I form an eccentric flange, t, having a break or interruption at its middle; and in this break, for the purpose of bridging over the space between the two ends of the flange, I pivot near its middle a dog or latch, V, such as shown in detail in Figs. 6 and 7. The journal of this latch formed thereon is extended through the needle, as shown in Fig. 7, and encircled by a spring, o, which tends to hold the latch in the position shown in full lines in Fig. 5.

The operation is as follows: At the instant the bundle is discharged the parts stand in the positions indicated by dotted lines in Fig. 5, the needle being fully elevated and the compresser fully depressed. As the needle retreats, its heel projection s, acting beneath the compressor, carries the same upward to its operative position. During this movement of the parts the roller r on the heel of the compresser rides over the upper side ot' the pivoted dog V, and finally, depressing the upper end of the dog, passes through beneath the upper end of the iiange t on the needle to the position shown by full lines in Figs. l and 5, the dogimmediately resuming its original position ICO under the inlinence of the spring. Asthe gavel is accumulated by the packers,it exerts apressure againstthe compressor T, forcing the same rearward to a slight extent, whereupon the roller r of the compressor, acting on the iiange t of the needle, forces the latter slightly upward,the eftect-beingtoturntheneedle-shaft and its crank f, which latter, through the pitman, trips the binder into action, as before eX- plained. The driving-gear, being setin motion, acts to positively elevate the needle. During this action the compressor T, being relieved from the support of the arm s, is sustained by the roller r, bearing beneath the flange t and dog V of the needle,which travel thereover. Owing to the eccentricity of this flange and dog with reference to the needle-shaft, they act during the elevation of the needle to depress the roller r, and thus force the compressor toward the needle, that it may act the more effectively in the compression of the grain. At the instant lthe binding operation is completed the advancing needle carries the pivot ofthe dog V beyond the roller r, whereupon the weight ofthe compressor causes the roller to pass over and above the tail end of the dog, the compressor falling to the position indicated in dotted lines in Fig. 5 to permit the discharge ot' the bundle, and the roller assuming such position that it may travel over the top ofthe dog, as before explained.

From the Vforegoing it will be understood that the compressor acts iirst to slightly advance the needle and thereby start the binder, and that the needle in its turn acts thereafter to sustain, advance, and finally release the coinpressor.

The binder deck or tabled/V is of substantially ordinary form and construction, being divided transversely into two parts, lying one in front andthe other in rear of the needle.

In order to avoid the troubles incident to the attachment and removal of this table in machines as ordinarily constructed, I adopt the construction shown in Figs. 1l and l2. The upper edge of the tablelies upon a stationary supporting-rail, w, as usual, and is provided on the under side with plates x, engaging in or beneath this rail to keep the table from rising. At or near the lower edge the table is provided with dowel-pins y, or a cleat, y', to engage the stationary supporting-bar z, whereby the table is prevented from sliding downward. Springactuated pawls c slide in plates secured to the under side of the table and enter the rail z, thus holding .the table down in place. On withdrawing these pawls the table is released, so that it may be lifted and drawn edgewise from the machine.

Having thus described my invention, what I claim isl. The knetter-driving shaft provided with a crank, the constantly-driven wheel O, revoluble freely around said shaft, the dog or pawl mounted in the crank and adapted to engage the wheel O, the spring to cause the engagement of the dog, a stop to hold the dog outfof action, and the needle-operating pit-man connected with said stop to disengage the same from the dog, substantially as described.

2. The knetter-driving shaft and its crank, in combination with the independentlyrevoluble driving-wheel O thereon, the intermediate dog or clutching device, S, the rock-shaft E, having the needle and the crank F fixed thereon, the longitudinally-yielding pitman R, connecting the needle-shaft crank with the k netter-shaft crank, and astop connected with said pitinan to hold the dog S out of action.

3. The knetter-dri ving shaft P and its crank, in combination with the loose driving-wheel O, the dog or clutch S between said wheel and shaft, the spring to cause the engagement of the dog, the compressible pitman and the stop connected therewith to hold the dog out of action, the needle-shaft having the crank connected to the pitman, the'compressor, and intermediate devices through which the compressor in retreating causes a slight advance of the elevated needle, whereby the pressure of the gavel against the compressor is caused to trip the binding mechanism into action.

4. In a grain-binder, the constantly-driven wheel O, the knetter-driving shaft l? and lits crank Q, and the dog or clutch device S, mounted o n the crank, in combination with the spring tending t0 cause the engagement of the dog, the slotted pitman-head coupled to the crank, the sliding stop k in said head, the pitman rod or body arranged to slidein the head and aetuate the stop, the spring tending to resist the sliding motion, and suitable mechanism through which the pitman is moved by the pressure of the grain.

5. The pivoted compressoroperating arm having a stud or roller, r, in combination with the vibratoly binding needle having the flanges and the switch V, substantially as described, whereby the retreat ofthe compressor under the pressure of the gavel is caused to impart a slight advance ofthe needle, andthe subsequent advance of theV needle underI the infiuence of its driving mechanism caused to sustain and finally release the compressor.

6. The pivoted vibratile needle having the eccentric flange, the pivoted dog, and the heeleXtension s, in combination with the compressorarm T, pivoted on the frame and provided with a stud or roller', i.
